You could look at the overall mean and the trimmed mean and see how much it changes, but that will be a function of your sample size and the deviation from the mean for your outliers.

0 There are better ways to estimate the standard deviation of the difference of two independent emperical datasets, when the probability distributions are unknown. You can use convolution, but a …

In Excel or Google Docs you can readily construct a Cumulative Distribution Function for the Normal distribution using the NORMDIST function (X, Mean, Standard Deviation). I am trying to do the sa...

Of course those need to be used in addition to the average and standard deviation. My objective is to create a number series that better captures the shape of a distribution than just using the average …

When I refer to all these 6 values, I am using STDEVP (or whatever exactly it is called in the English version of Excel--I got various hits for the "whole" stdev variant). What should I use for calculating a …

From the sample you compute a) the degrees of freedom, which here is one less than the number of observations (n), b) the average vaue of the sample (X-bar), the sample standard deviation (s). …

I have a monthly average for a value and a standard deviation corresponding to that average. I am now computing the annual average as the sum of monthly averages, how can I represent the standard

I want to find the standard deviation of the percentages, but weighted for their data volume. ie, the first and last data points should dominate the calculation.

I have three variables some of which are occasionally 0 which is a na and not a sample. I would like to calculate the standard deviation of the remaining two items but there isn't a deviation if like
